Remaining:

Rock,Bug,Psychic,Fairy,Ghost,Ice,Fighting(not Possible), Normal,Dragon,Poison,Steel (11)

Taken:

Electric,Fire,Water,Flying,Ground,Grass,Dark,(7)

Total Type:18

Possible it would be Psychic Or Rock or maybe Normal

Rock stands for a Hard stone and Criminals have a hard Attitudes

Psychic For a clear Minded Leader and every Criminals have a very foggy Mind And Gym leaders are very calm when battling

Normal for having Rough attitudes while normal may have weakness to Fighting types but can learn some few Fighting moves

Idea For Gym leader type: Psychic,Rock,Normal
